1.8Ghz, correct.
I guess if you feel the need to have Quad-Core, it's alright. But you can get dual-core AMD chips with 45W up to 2.3ghz and 65w up to 2.7ghz. In non optimized apps, these would perform better. And even in programs that use all 4-cores, the extra speed of the dual-chips would probably only have performance lagging behind a little. But that extra speed from Quad would be worth it if you mostly do optimized programs, I suppose. There's a market for these, just not very big I think is what I'm trying to say.
